Demakes Family YMCA

As the structural engineer of record, SGH designed the steel-framed structure for the new YMCA building. Highlights of our design include:

• Exposed steel framing, including concentric braced frames that coordinate with the architectural design and program requirements
• Long-span roof structures over the indoor pool and basketball court
• Suspended mezzanine to support the elevated track
• Shallow foundations on a preloaded site to improve allowable bearing capacities
• Structural support for special equipment, such as basketball hoops
• Coordination with the swimming pool provider

SGH also consulted on the building enclosure design featuring curtain walls; EIFS, metal panel, and concrete masonry cladding; and low-slope roofing. Highlights of our work include:

• Reviewing the proposed building enclosure design for airtightness, watertightness, durability, reliability, constructability, and general suitability
• Helping develop details for the various enclosure systems and to integrate them with
  each other
• Evaluating interior wall assemblies that separate the high-humidity natatorium from other interior spaces and proposing ways to mitigation condensation
• Performing construction phase performance testing, including whole building air leakage testing of the natatorium
